The present paper describes and illustrates the female of two new species of the genusTarsonemus from Germany. 1. Tarsonemus longisetaceus sp. nov. (figs. 1--6) This new species resembles Tarsonemus waitei Banks 1912 and T. idaeus Suski 1968, butdiffers from the latter two in: 1. setae e (ca 30μm) of the tergite Ⅳ smooth, slender, finelytarpered and distinctly longer than setae d, f and h; 2. tibiatarsus I with solenidia T_iβ andtarsus Ⅱ with T_aβ; 3. tegula cresent-shaped. Holotype , paratypes 2 , 81. Ⅷ. 1989. collected by Zhang Xin-hu on grape in Muel-heim (49. 7°N, 6. 7°E). The type specimens are deposited in the Institute of Grape Protection,Federal Bilogical Research Centre for Agriculture and Forestry, Bernkastel-Kues, Germany. 2. Tarsonemus telaaki sp. nov. (figs. 7--12) The female adult of the new species is similar to Tarsonemus piliger Schlechtendal 1898,but is distinguished from the latter by: 1. apodeme Ⅳ s in shape 2. setae 3b inserted at theposterior one fifth of the apodeme Ⅳ; 3. femur I with 4 setae; 4. having T_iβ on tibiatarsus I and T_aβ on tarsus Ⅱ. Holotype , paratypes 8 , 6. Ⅸ. 1989. Wolf; 11. Ⅸ. 1989. Kroev; 18. Ⅸ. 1989.Ahrweiler; 9. Ⅹ. 1989 Wehlen (9. 7°N, 6. 7°E) on grape, collected by Zhang Xin-hu.
